[Asterisk Development Team]

The Asterisk Development Team has announced security releases for Certified
Asterisk 1.8.28 and 11.6 and Asterisk 1.8, 11, 12, and 13. The available
security releases are released as versions 1.8.28.cert-4, 1.8.32.2, 11.6-cert10,
11.15.1, 12.8.1, and 13.1.1.

These releases are available for immediate download at

The release of these versions resolves the following security vulnerabilities:

* AST-2015-001: File descriptor leak when incompatible codecs are offered 

                Asterisk may be configured to only allow specific audio or   
                video codecs to be used when communicating with a            
                particular endpoint. When an endpoint sends an SDP offer     
                that only lists codecs not allowed by Asterisk, the offer    
                is rejected. However, in this case, RTP ports that are       
                allocated in the process are not reclaimed.                  
                                                                              
                This issue only affects the PJSIP channel driver in          
                Asterisk. Users of the chan_sip channel driver are not       
                affected. 

* AST-2015-002: Mitigation for libcURL HTTP request injection vulnerability 

                CVE-2014-8150 reported an HTTP request injection             
                vulnerability in libcURL. Asterisk uses libcURL in its       
                func_curl.so module (the CURL() dialplan function), as well  
                as its res_config_curl.so (cURL realtime backend) modules.   
                                                                             
                Since Asterisk may be configured to allow for user-supplied  
                URLs to be passed to libcURL, it is possible that an         
                attacker could use Asterisk as an attack vector to inject    
                unauthorized HTTP requests if the version of libcURL         
                installed on the Asterisk server is affected by              
                CVE-2014-8150.
